How to convert std::thread::id to string in c++?
auto myid = this_thread::get_id();stringstream ss;ss << myid;string mystring = ss.str();
Actually std::thread::id
is printable using ostream
(see this).
So you can do this:
#include <sstream>std::ostringstream ss;ss << std::this_thread::get_id();std::string idstr = ss.str();
"converting" std::thread::id
to a std::string
just gives you some unique but otherwise useless text. Alternatively, you may "convert" it to a small integer number useful for easy identification by humans:
std::size_t index(const std::thread::id id){ static std::size_t nextindex = 0; static std::mutex my_mutex; static std::map<std::thread::id, st::size_t> ids; std::lock_guard<std::mutex> lock(my_mutex); if(ids.find(id) == ids.end()) ids[id] = nextindex++; return ids[id];}
